The Illinois Natural History Survey Mollusk Collection contains over 105,400 catalogued specimens, most of which were collected in Illinois and the southeastern United States. The collection is 90% freshwater species (mussels, fingernail clams, and snails) and 10% terrestrial species (snails). Most of the specimens were collected as a result of various faunal surveys conducted by INHS biologists from the late 1800's until the present. The early collections were made by such naturalists as John W. Powell, Robert Kennicott, Richard E. Call, William A. Nason, Frank C. Baker, Robert E. Richardson, and Charles A. Hart. |
